A electrocardiogram at rest (ECG) is a painless examination that measures the electrical activity of your muscle. It involves placing small sensors on your chest, arms, and legs. These electrodes transmit signals to a machine that creates a tracing of your heart's beat. An ECG at rest can help your doctor assess various cardiovascular diseases, such as arrhythmias. It is often conducted as part of a physical examination.
Exercise Stress Test Electrocardiography (ECG)
An exercise stress test electrocardiography (ECG) is a valuable tool used to evaluate the heart's function during elevated physical effort. During the test, patients bike on a stationary bicycle while their ECG is tracked. This allows cardiologists to observe any abnormalities in the heart's rhythm or electrical activity that may not be present at rest.
The test can help reveal a range of conditions affecting the heart, such as coronary artery disease, arrhythmias, and heart failure. By observing how the heart responds to physical exertion, doctors can get a more comprehensive understanding of its overall health and functionality.
Continuous Holter ECG Monitoring
A continuous Holter electrocardiogram recording, also known as a Holter monitor, is a portable device that records your cardiac rhythm over an extended period. Typically worn for one to three days, the Holter monitor records your heart rhythm throughout everyday activities. This allows physicians to observe any abnormalities that may not be evident during a routine electrocardiogram (ECG) test conducted in a clinical setting. The information gathered from the Holter monitor can be essential for understanding a variety of heart conditions, including arrhythmias, electrical disturbances, and other electrophysiological issues.

If your physician suspects a heart rhythm problem, they may recommend a Holter monitor to provide detailed information about your cardiac activity over time.

Evaluation of Cardiac Function During Exercise Testing (ECG)
During exercise testing, electrocardiography (ECG) plays a crucial role in assessing cardiac function. As the individual exercises, their heart rate and rhythm increase. The ECG provides real-time representation of these changes, permitting clinicians to identify any irregularities in electrical activity.
These abnormalities may include ST-segment depression, T-wave alterations, and arrhythmias, which can suggest underlying cardiac disease. By analyzing the ECG during exercise, clinicians can assess the working capacity of the heart and uncover potential risks associated with physical activity.
Ambulatory ECG Monitoring for Symptom Assessment
Ambulatory ECG monitoring is a valuable tool for assessing symptoms that may be related to cardiac activity. A portable ECG device, commonly worn for 24 to 48 hours, records the patient's electrical 24 hr heart monitor signals continuously. This prolonged monitoring facilitates healthcare professionals to detect transient abnormalities in heart rhythm that may not be observed during a standard, short-term ECG test in the clinic. The recorded data can then be analyzed by a cardiologist to present valuable insights into the patient's {underlying{ conditions and guide treatment decisions.
Benefits of ambulatory ECG monitoring include its ability to:
- Capture infrequent arrhythmias
- Determine the impact of daily activities on heart rhythm
- Present objective evidence for symptom-related concerns
- Influence treatment plans and medication adjustments
